Barcode readers (top) are designed to reveal and read the data within a code. Some barcode reader
software may provide print quality metrics useful for process control. Barcode verifiers (down), by
contrast, grade codes according to international standards and generate printed reports to help
Verification reduces product returns, packaging waste, and other expenses.
Barcode verification is an essential quality control tool to ensure a barcode’s complete scannability along
the supply chain.
Many producers already monitor the quality of their codes using process control metrics
(PCM) and validate their data using software on their barcode readers. But PCM test results are unique to a
reader’s particular set-up, including lighting. Barcode verifiers, by contrast, ensure codes are marked
correctly and meet an industry’s—rather than an individual producer’s—quality threshold.
A verifier checks
all quality parameters, uses a specific lighting set-up, and requires regular calibration.
